How to use with mathjs?

[LorhanSohaky]

I trying

import { create, all } from 'mathjs'

const math = create(all, {})

const expressionFromUser = 'sum(1,1)'

const result = safeEval(expressionFromUser.replace(/sum/gi, `math.sum`), { math })

but I am getting the following error:

TypeError: x.constructor is undefined
